Wiring that connects to the engine control unit (ECU) may not fit properly, and not maintain a secure connection. This can lead to vehicle stalling, or the inability to start the engine. This can increase risk of a crash.

The switch that operates the brake lights and allows the gear shift lever to be unlocked from the park position may not be installed properly. As a result, the brake lights may stay illuminated, and the shift lever may be able to be moved from park without depressing the brake pedal. Both scenarios create a risk of accident or injury.

The passenger frontal air bag assembly is deployed by an inflator which contains propellant that makes the air bag deploy. This propellant may degrade over time, especially when exposed to humidity and temperature cycling. As a result, the inflator may rupture on deployment, which can send metal shrapnel through the air bag, striking vehicle occupants. This could result in serious injury or death.

The passenger frontal air bag may deploy when it should be deactivated with a child seat installed in the passenger front seat. This is due to a seat bracket becoming deformed when installing the child seat's child restraint system. The deformed bracket will send improper information to the occupant classification system which would allow the air bag to remain powered in an accident. This could result in increased risk of injury to the child in the seat.

The passenger frontal air bag may fail to deploy in an accident. This can occur due to the passenger seat occupant classification system not being properly calibrated, and may not detect a passenger present in the seat as appropriate. This would increase risk of occupant injury in an accident.

The brake system may not stop the vehicle effectively, or may operate erratically during events which trigger the anti-lock brake system or vehicle dynamic control system. This can cause extended stopping distances or loss of vehicle control, resulting in an accident.
